* Nazzaf's: https://www.thingiverse.com/thing:1198514
* Barspin: https://www.thingiverse.com/thing:113764

Nazzaf's frame made it easy to insert and remove the camera, had the openings placed correctly for Hero 3+ mics, and had bigger holes for the buttons (which I liked since I would be using this while skiing with thick gloves). However, the camera did not fit in the frame tightly and would rattle.
